To maximise space in a very small bathroom (1.8m x 1.7m), I am considering moving the toilet to the opposite corner from where it is presently situated. Is there any paractical limitation to length/run-off of the waste pipe taking into consideration that two 90deg bends are introduced into the run (all above floor level) - don't want 'stools' stalling halfway thru' the run... 
Many thanks
